PRIORITY CLAIM

This application claims priority to U.S. Provisional Patent Application Ser. No. 62/828,421, filed Apr. 2, 2019, and U.S. Provisional Patent Application Ser. No. 62/872,296, filed Jul. 10, 2019, the entire contents of each of which are incorporated herein by reference and relied upon.

BACKGROUND

Pain in the abdominal region is often debilitating, and is difficult to relieve topically using heat- or cold-based topical therapies without significantly limiting mobility. While some wearable devices are available, they perform poorly, often completely failing to maintain an initial position of an included thermal pack with even the slightest movement by the wearer.

A need persists for devices enabling localized thermal treatment of pain in the abdominal/pelvic area that do not significantly limit mobility of the user.

In some embodiments, the undergarment 10 further comprises a third front panel 300 disposed between the second front panel 100 and a user when the undergarment 10 is in use by the user. In some embodiments, the undergarment is seamless.

Referring now to FIGS. 8-14 , an undergarment 20 according to another embodiment of the present disclosure comprises a unitary piece of material including a front portion 2000, a rear portion 5000A-5000B, a gusset portion 6000 bridging the front portion 2000 and the rear portion 5000A-5000B, and a pouch cavity 3500 formed between an outer panel layer 2500A and an inner panel layer 2500B.

The front portion 2000 includes a proximal edge 2300 and a pouch opening 3550 distal to the proximal edge 2300 and formed in the outer panel surface 2500A. The front portion 2000 includes an outer panel layer 2500A and an inner panel layer 2500B formed for example, by folding a single piece of material along fold line 2300 as shown in FIGS. 10-11 and joining edges of the folded piece together. The shape of the pouch cavity 3500 may therefore be defined by the shapes of the outer panel layer 2500A and the inner panel layer 2500B and may, for example, include a gusset pouch portion between an outer gusset layer 6000A and an inner gusset layer 6000B.

The pouch cavity 3500 may include a pouch opening 3550 formed in the outer panel layer 2500A. In other embodiments, the pouch opening 3550 is formed in the inner panel layer 2500B. In either embodiment, the pouch opening 3550 may be surrounded or partly surrounded by pouch opening stitching 3700 to prevent the material from fraying at the pouch opening 3550. In other embodiments, the pouch opening 3550 may be thermally sealed to prevent fraying. In some embodiments, such as those consistent with the embodiment specifically shown in FIG. 8 , the pouch opening 3550 is horizontal or substantially horizontal (e.g., is parallel or substantially parallel with the proximal edge 2300). In other embodiments, the pouch opening 3550 is vertical or substantially vertical (e.g., is perpendicular or substantially perpendicular to the proximal edge 2300).

As shown in FIG. 9 , the unitary piece of material may be formed into the undergarment 20 by joining a right rear portion edge 2400A to a left rear portion edge 2400B with a rear seam 5100, and by joining the gusset edge 6200 to the distal edge 5200A/5200B of the left rear portion 5000B and/or the right rear portion 5000A with a gusset seam 5150. In the embodiment shown in FIG. 9 , the rear seam 5100 divides the right rear portion 5000A and the left rear portion 5000B substantially evenly, Although in other embodiments the rear seam 5100 maybe offset from the midline of the undergarment 20. Thus, in the embodiment shown in FIG. 9 , the gusset seam 5150 Joins the gusset edge 6200 to both the left posterior distal edge 5200B of the left rear portion 5000B and the right posterior distal edge 5200A to the right rear portion 5000A.

Once formed, the undergarment 20 includes a right leg hole 2100 and a left leg hole 2200 for accommodating a right leg RL and a left leg LL of a user. The right leg hole 2100 is surrounded or partially surrounded by right leg hole stitching 2600 to prevent a thermal pack from exiting the pouch cavity 3500. The left leg hole 2200 is surrounded or partially surrounded by left leg hole stitching 2700 to prevent a thermal pack from exiting the pouch cavity 3500.

The present disclosure provides kits comprising an undergarment as disclosed herein and at least one thermal pack for inserting into the pouch of the undergarment. In some embodiments, the thermal pack is a cooling pack. In some embodiments, the thermal pack is a heating pack. In some embodiments, the kit includes at least one cooling pack and at least one heating pack. The thermal packs may be single-use or multiple-use heating packs or cooling packs. In some embodiments, the undergarment is washable and may be used more than once. In other embodiments, the undergarment is intended for only a single-use and may be discarded after that use.

Undergarments and kits including undergarments consistent with the present disclosure are useful for reducing abdominal pain. In general, and with reference to FIG. 7 , a method of reducing abdominal pain includes positioning an undergarment 10/20 of the present disclosure about the lower torso/pelvic area T of a subject, inserting a thermal pack into the pouch 350 or the pouch cavity 3500 of the undergarment, and leaving the thermal pack in the pouch 350 or the pouch cavity 3500 for a period of time to reduce the abdominal pain.

The thermal pack may be a heating pack or a cooling pack, and the thermal pack may be intended for single use or multiple uses.

The thermal pack is inserted into the pouch 350/pouch cavity 3500 and positioned within the pouch 350/pouch cavity 3500 to be adjacent to a pain locus experienced by the subject. The pain locus may be associated with an abdominal area of the subject, with a vaginal area of the subject, and/or with a perineal area (e.g., perianal area) of the subject. Tension applied to the thermal pack by the first front panel 200 and second front panel 100, or by the outer panel layer 2500A, draws the thermal pack towards the subject. At the same time, the third front panel 300 or the inner panel layer 2500B prevents the thermal pack from making direct contact with skin of the subject, preventing injury or discomfort to the subject's skin such as burns, irritation, or frostbite. The tension from the first front panel 200 and second front panel 100, or from the outer panel layer 250A, also effectively Preserves the position of the thermal pack relative to the subject's anatomy, even when the subject moves (e.g., shifts position, walks, bends over, etc.).

Any pain experienced by a subject between the umbilical area and the perineal area (e.g., perianal area), in the abdominal area, and/or in the lower back area may be reduced by undergarments and thermal packs disclosed herein. For example, undergarments and thermal packs consistent with the present disclosure may be used to reduce pain caused by child birth, a cesarean section procedure, an appendectomy procedure, a vasectomy procedure, a hernia repair procedure, an episiotomy correction procedure, a pelvic organ prolapse (“POP”) repair procedure, a stress urinary incontinence (“SUI”) repair procedure, a gynecological procedure (e.g., a hysterectomy procedure, an adhesiolysis procedure, a cervical biopsy procedure, a colporrhaphy procedure, a colposcopy procedure, a dilation and curettage (“D&C”) procedure, an endometrial ablation procedure, an endometrial biopsy procedure, a uterine biopsy procedure, a fluid-contrast ultrasound (“FCUS”) procedure, a hysterosalpingography procedure, a hysteroscopy procedure, a myomectomy procedure, an oophorectomy procedure, a pelvic ultrasound procedure, a pelviscopy (pelvic laparoscopy) procedure, a selective salpingography procedure, a uterine suspension procedure, a vaginal vault suspension procedure, a toluidine blue dye test procedure, a trachelectomy procedure, a tubal ligation procedure, a uterine fibroid embolization (“UFE”) procedure, or a vulvectomy procedure), a hemorrhoid or a hemorrhoid correction procedure, a cancer, a sexually transmitted infection, an anal fissure, a muscle spasm (e.g., proctalgia fugax and/or levator syndrome), an anal fistula, a perianal hematoma, a rectal ulcer (e.g., solitary rectal ulcer syndrome), a thrombosis (e.g., a thrombosis hemorrhoid), tenesmus, inflammatory bowel disease, proctitis, a perineal, perianal or perirectal abscess, fecal impaction, rectal prolapse, abdominal pain, labial pain, perineal pain, pain resulting from fertility treatments (e.g., injection site pain, bloating, sensitivity), Bartholinitis, post-surgical pains (e.g., pain resulting from hysterectomy, pain resulting from Bartholin marsupialization, or pain resulting from vaginal tightening due to, e.g., vaginoplasty, perineoplasty, labia majora plasty, labiaplasty, hymenoplasty, or vulvar lipoplasty), pain related to endometriosis, plastic surgeries, post-D&C procedure, post-harvesting of eggs for freezing, lower back pain, hemorrhoids, gender reassignment surgeries, yeast infections, pain from Bartholin cyst, marsupialization of Bartholin cyst, surgical drainage of Bartholin cyst, pain and itching related to menopause, pain and itching related to vulvar cancer, pain associated with sex, pain and itching associated with sexually transmitted disease, vaginosis, pain and abdominal swelling associated with menstrual cycles, bladder inflammation, interstitial cystitis, cystitis, pain related to urinary tract infections, pelvic inflammatory disease, pain and/or abdominal swelling related to pelvic or abdominal adhesions, pain and/or abdominal swelling related to ovarian cysts, pain and/or abdominal swelling related to uterine fibroids, pain and/or abdominal swelling related to tumors, pain and/or abdominal swelling related to kidney stones, pain and/or abdominal swelling related to PMS, pain and/or abdominal swelling related to vulvodynia, and/or pain and/or abdominal swelling related to adenomyosis.
